11 are provided with seed inlet 14, are offered provided with depositing of being connected with seed inlet 14 in kind of room 111, the shell 11 in the shell 11
Charge seed area 112；The cap 15 is provided with air inlet 151, makes its shape for connecting the Xi Zhong mechanisms 40 and the housing 10
Into an air flue；
Fig. 1 be refer to Fig. 6, the Xi Zhong mechanisms 40 include blower fan and pipeline, the air inlet 151 passes through the pipeline
It is connected with the blower fan；The sowing mechanism 20 is located in the housing 10, including seeds sucker 21 and discharge plate 22, the seeding
Disk 22 is located between the seeds sucker 21 and the cap 15；The seeds sucker 21 is provided with multiple suction holes 211, the seeding
Disk 22 is provided with multiple feed outlets 221 corresponding with the suction hole 211；The rotating mechanism 30 is rotatably located at the shell
Middle part in body 10, the rotating mechanism 30 is used to drive the sowing mechanism 20 to turn to the area 112 of charging seed.
The implanted device has the effect of continuous seeding, can improve the utilization rate of sowing mechanism, reduces seeding process seed
Seed broken rate, simultaneously effective limit single sowing quantity.
The suction hole 211 is provided close at the outer ledge of the seeds sucker 21 along the circumferential direction.In embodiment, with jade
Exemplified by rice seed, the main design parameters of the seeds sucker 21 include the thickness of discharge plate 22, the diameter of suction hole 211, angle of countersink.Root
According to the contour structures feature of corn seed, the suction hole 211 of the seeds sucker 21 uses bellmouth, the thickness of the suction hole 211
Degree need to be more than most long corn seed, and aperture should be greater than most wide corn seed, corn seed showing in the suction hole 211
It is intended to as shown in figure 5, Size calculation formula is as follows：
Wherein：
a1--- corn seed maximum length value, the corn seed more than 98% takes a between 8~13mm1=13mm；
b1--- corn seed width, less than the full-size on seed width, take；b1=8mm；
Z --- seed width b in taper hole1Following length, general 1~2mm, takes z=1.5mm；
The half of corn seed is assumed to be cone, and bottom circle is set to maximum gauge value Cmax, Cmax=7.5；
Dw=15mm
Each data, which are substituted into formula 1,2, to be obtained：
Release h>24.6, h=25mm is taken, then θ=33.4 °.
X=6.7mm is released, x=7mm is taken, then the thickness of discharge plate 22 is 25-7=18mm.
To sum up：Axis of great circle Dw=15mm, axis of small circle D=5.5mm.
When the seeds sucker 21 and the housing 10 are closely coupled, the seeds sucker 21 and the gas of the housing 10 formation
Indoor air pressure makes the formation of seeds sucker 21 or so the pressure differential, so that the suction that seed can be tightly by suction hole 211
It is attached in the suction hole 211.Hole diameter is bigger, and throughput is bigger, and maximum pressure is bigger, and the ability of absorbed seed is just
It is stronger, but 2 are also enhanced compared with seedlet while adsorbed probability, it is preferred that design takes D=5.5mm, then actual type hole
